Question

我想安装docker-ce，但无法启动

我以这种方式安装docker-ce：

sudo yum install docker-ce

我的系统类型：

Linux version 3.10.107-1-tlinux2_kvm_guest-0046 (root@TENCENT64.site) (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC) ) #1 SMP Wed Dec 27 10:57:04 CST 2017

docker版本：

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

我的daemon.json（/etc/docker/daemon.json）不存在，当我创建一个内容为'{}'的daemon.json时，也报错

我尝试了一些方法：

清除/ var / lib / docker
重新安装docker-ce

docker的旧版本docker和docker-io是正常的，但是没有ip和端口映射，所以我现在使用docker-ce。

如何解决此问题？

可以使用两种不同的方法启动Docker：

通过systemctl，这是推荐的方式
直接通过docker daemon bin：dockerd，这不是推荐的方式

但是，当您直接启动docker守护程序时（即不使用systemctl），systemctl无法知道守护程序的当前状态。

所以我的猜测是，在安装后，docker守护程序以某种方式部分启动并失败。
要检查是否是这种情况，只需运行：

sudo ps -aux | grep dockerd

然后杀死附加到docker守护程序的所有进程。
完成后，您应该可以直接通过systemctl启动docker。
